During storage, the square-root-of-time (\(\sqrt{t}\) ) dependent capacity fade points to a self-limiting kinetic behind this continuous growth process [1]}, [2]}, [3]}, [4]}, [5]}. Diffusion of localized electrons, e.g. as neutral lithium interstitial atoms [6]}, [7]}, emerged as most likely growth limiting mechanism as it best captures the experimentally observed voltage dependence [8]}, [9]}, [4]}.
